Sun Su-yun · Jisuanji gongcheng · 2008
This paper brings forward a QoS evaluation model of Web service by adding a QoS authority part on the existing UDDI criterion. It defines a set of QoS categorization tModels, and introduces the concept of QoS quantification. It uses a monitor mechanism initiatively and a feedback mechanism from service consumers for evaluating and adjusting QoS value of Web service dynamically in UDDI. The impartiality, trustworthiness, and real-time characteristics of QoS information are ensured.
